Complaints about sleep and sleepiness are widespread and are closely associated with dysfunctional beliefs about sleep, disturbed sleep hygiene and anxiety-depressive experiences (Perlis et al., 2011, Riemann et al., 2017, Sateia et al., 2017), however, the specific role and interactions of these factors are understudied.

The aim was to reveal the relationship between cognitive, emotional and behavioral factors of subjective sleep quality, sleepiness and typical patterns of nighttime sleep in the normative sample.

224 people 18-47 years old without diagnosed sleep disorders answered questions about their sleep patterns, filled in the Insomnia Severity Index, Dysfunctional Beliefs About Sleep Scale (Morin, 1993), Behavioral Factors of Sleep Disorders Scale (Rasskazova, 2020), Epworth Sleepiness Scale (Johns, 1991), Glasgow Thought Content Inventory (Harvey, Espie, 2004), Hospital Anxiety and Depression Scale (Zigmond, Snaith, 1983).

The poorer subjective quality of sleep is predicted by more dysfunctional beliefs about sleep, cognitive arousal and disturbed sleep hygiene (R2=45.1%). The negative effect of cognitive arousal on sleep quality is higher in people with sleep hygiene disturbances (ΔR2=1.4%, p<.05). Only disturbance of sleep hygiene is a predictor of sleep duration, sleepiness and the experience of insufficient sleep (R2=9.9%-12.2%), while cognitive arousal (R2=23.4%) and (in people with higher sleep hygiene disturbances, ΔR2=3.5%, p<.01) negative emotions predict poorer sleep efficacy.

Both relationship between cognitive arousal and poorer subjective sleep and relationship between anxiety, depression and poorer sleep efficacy are stronger in people with poorer sleep hygiene. Research is supported by the Russian Foundation for Basic Research, project No. 20-013-00740.

High prevalence of dysfunctional beliefs about sleep and poor sleep hygiene in population (Perlis et al., 2011, Riemann et al., 2017) allow suggesting (Rasskazova, Tkhostov, 2012) a socially determined low value of sleep relative to other activities and demands.

The aim was to reveal the role of the relative value of sleep and subjective quality of sleep in people without sleep disorders.

172 participants 18-62 years old without diagnosed sleep disorders answered three items about their relative sleep value, filled Insomnia Severity Index, Dysfunctional Beliefs About Sleep Scale (Morin, 1993), Behavioral Factors of Sleep Disorders Scale (Rasskazova, 2020) and Hospital Anxiety and Depression Scale (Zigmond, Snaith, 1983)

56.3% -65.3% participants tend to neglect sleep for the sake of other activities in conflictual situation independent on gender and age. Sleep neglect is associated with poorer subjective sleep indirectly – through poor sleep hygiene, depressive emotions and postponement of the time to get up in the morning (β=.02-.09; 95%CI [.01-.17]). High value of healthy sleep is associated with poorer sleep quality if it leads to higher dysfunctional sleep beliefs and sleep rituals (indirect effects β=.04-.16; 95%CI [.01-.23]), but with better sleep quality if it leads to better sleep hygiene in the evening and less delay in getting up in the morning (β=-.04 - -.02; 95%CI [-.08-.00]).

Relative value of sleep might play a different role in the sleep regulation depending on which long-term beliefs, emotions, and behaviors it provokes. Research is supported by the Russian Foundation for Basic Research, project No. 20-013-00740.

Sleep-related complaints are among the most common during pandemic, along with anxiety and depression (Huang, Zhao 2020, Rajkumar 2020). Their prevalence is associated with anxiety about the pandemic (Roy et al., 2020), online information search (Moghanibashi-Mansourieh, 2020, Wang et al., 2020).

The aim was to reveal relationship between the type anxiety and coping during pandemic and sleep-related complaints after 3-4 weeks of lockdown.

203 adults aged 18 to 59 years filled situational version COPE (Carver et al., 1989) and scales measuring anxiety of infection and pandemic consequences (Tkhostov, Rasskazova, 2020) in the mid-April 2020 after 2-3 weeks of lockdown in Russia. After 3-4 weeks, they filled in a modified insomnia severity index (Morin, 1991) appraising how much worse their sleep and daytime functioning during this period (Cronbach’s alpha .62-.73).

Prevalence of sleep and day functioning related complaints during lockdown varied 19.3%-30.5%. Complaints were associated with anxiety only if it reaches dysfunctional level (interfering with daily activities, r = .17-.34, p <.05) and coping strategy of mental disengagement (r = .15-.19, p <.05). Sleep complaints were related to substance use to cope with lockdown problems while complaints on daytime functioning correlated were more common among young respondents (r = -0.22, p <0.01).

Complaints about poor sleep during a pandemic are not related to the general severity of pandemic anxiety, but to the dysfunctional level of anxiety and attempts to avoid it. Research is supported by the Russian Foundation for Basic Research, project No. 20-013-00740.
